Abstract

A touch panel system includes a signal generator configured to generate a reference signal and one or more channels. Each of the channels comprises a sensing unit configured to sense a touch thereon to output a sensing signal indicative of the touch; and a delay unit configured to adjust the reference signal based on a delay compensation value to compensate delay of the reference signal caused by the difference of distance between the signal generator and the channel. Further, each of the channels comprises an operation unit configured to perform an operation on the sensing signal and the reference signal from the delay unit to produce an operation result representing difference between the sensing signal and the adjusted reference signal; and a controller configured to determine the delay compensation value of the delay unit in each channel based on the voltage signal from the operation unit.
